The object of my invention is to provide a mine locomotive with a movable platform which can be turned up against the end of a mine locomotive so as to allow the locospace, such, for instance, the cage of a mine elevator. This object I attain in the following manner. reference being had to the accompanying drawings, in which" Figure 1 is a view of one end of a locomotive showing my improved operators platform in position to be occupied by an operator;

Fig. 2 is a plan view, tl e platform being in the same position as in Fig. 1;

Fig. 3 is an end view; and

Fig. 4 is a View similar to Fi 1, showing the platform in the raised position. I

Referring to the drawings, 1 is the frame of a mine locomotive mounted on wheels 2 shown by dotted lines in Fig. 1, and mounted on the frame is a body 3 containing, in the present instance, the usual storage batteries.

Pivoted at 4 to the frame 1 is a rectangular frame 5 which is open at the center, the frame being made angle shape in the resent instance and having a portion 6 at each side which extends past the pivot 4 and rests against the underside of a flange 7 of the main frame 1.

Mounted on one of the side members of the frame 5 is an operators seat 8.

Pivoted at 9 to the lower portion of the main frame 1 is a platform 10. The outer end of this platform is suspended by a. hinged joint 11 to a plate 12 which is, in turn, pivoted at 13 to the upper frame 5. This plate 12 has a strengthening flange 14 at each side.

The platform 10 is turned up at each side as at 15 to form guards for the operator. These guards also tend to strengthen the plat form.

When the parts are in position as shown in Fig. l, the platform 10 is supported not only by its hinged joint 9 but by the upper frame 5 which is held in its horizontal position by the flange 7 of the main frame. The operator can either stand on the platform 10 or can use the seat 8 which is carried-by the upper frame 5.

Then it is desired to reduce the length of the locomotive, such, for instance, when it is necessary to run the locomotive onto the platform of a mine elevator, the platform is turned on its pivots to the position shown in Fig. l. The flanges of the platform 10 pass frame; means for pivotally connecting on each side of the main frame 1 and the driving wheels 2, these flanges being cut away so as to fit against the body 8. The frame 5 ext-ends up against the end of the body but does not extend above the same to such extent as to interfere with the movement of the locomotive in a comparatively shallow room or passage.

While I have shown a solid plate connecting the outer ends of the platform and a rec tangular upper frame, it will be understood that the'construction may brain the form of an open frame without departing from the essential features of my invention.

I claim:

'1. The combination in a mine locomotive, of a nected to the main frame at one end; and a frame located above the platform and also pivotallyconnected to the main frame, the outer end of the platform and the upper frame being pivotally connected together so that the platform can be lowered into posi tion to be occupied by .an operator or turned up against the end of the locomotive.

2. The combination in a mine locomotive, of a main frame; arectangular frame open at the center and pivotally connected to the main frame; a platform below the reetangular frame and also pivotally connected to the main frame; and a plate connecting the outer ends of the platform and the rectangular frame, said plate being pivotally connected to both the platform and the rectangular frame, so that when the platform is lowered and in position to be occupied and used by an operator the plate will form a guard, and

when raised the plate will assume a position within the rectangular frame.

' 3. The combination in a mine locomotive,

of a main frame; a platform'pivotally connected to the lower end of the main frame and having side flanges which when the platform is raised extend on each side of the main frame; an upper frame located above the platform and pivotally connected to the I the outer end of the platform to the outer end of the frame; and a seat secured to the upper frame, the pivots being such that when the platform is lowered it can be occupied by an operator, and when raised it will rest against the platform, allowing the upper frame to be located against the end of the locomotive.

4. The combination in a mine locomotive, of a main frame; a platform pivotally conmain frame;'a platform pivotally connected to the lower end of the main frame; anupper frame above the platform and also pivotally connected toithemain frame, said upper frame having portions extending back of the pivots and resting against the projection of the mam frame so as to hold said rectangular upper frame in a horizontal position; and a plate connecting the upper the platform and said rectangular frame can be turned up against the end of the locomotive.
